摘要： A method is provided for calibrating a surgical biopsy system. The biopsy system includes a biopsy instrument and control unit. The biopsy instrument includes a piercer, rotatable cutter, and a port for receiving tissue samples. The method comprises the steps of translating the cutter distally until the translation of the cutter is stopped at an extended position and recording the extended position. The cutter is then translated from the extended position proximally until the translation of the cutter is stopped at a retracted position proximal to the extended position. The retracted position is recorded. The method further comprises the step of rotating the cutter to a rotation speed while the cutter is located at the retracted position and, if determined that the rotation speed is within a predetermined rotation speed range, a feedback signal is provided on the display allowing the operator to progress to the next procedural step.

摘要： The present invention is a control apparatus for removing at least one tissue sample from a surgical patient using a surgical biopsy device. The biopsy device comprises an elongated piercer having a piercer lumen extending therethrough, and a cutter rotatably and axially positionable relative to the piercer. The piercer has a port for receiving and transferring the tissue sample into the piercer lumen. The biopsy device further comprises a rotation motor for rotating the cutter and a translation motor for translating the cutter in the axial direction. In one embodiment of the present invention, the control apparatus comprises a computing device for the coordinated control of the rotation and translation motors. The control apparatus further comprises a first sensor operationally connected to the rotation motor for supplying a rotation signal to the computing device for measuring the rotational speed of the cutter. The control apparatus further comprises a second sensor operationally connected to the translation motor for supplying a translation signal to the computing device for measuring the translational position and translational speed of the cutter. The control apparatus further comprises a first driver for driving the translation motor in response to a translation command from the computing device, and a second driver for driving the rotation motor in response to a rotation command from the computing device. The control apparatus automatically modifies the rotational speed and the translational speed of the cutter in response to the translational position and rotational resistance acting on the cutter.

摘要： A surgical stapler is provided which is insertable through an endoscopic tube to enable a surgeon to staple a hernia patch to tissue inside a body cavity. The endoscopic surgical stapler includes a staple cartridge pivotally mounted on the distal end of a support tube extending from a handle provided with an actuator mechanism for actuating a staple forming mechanism inside the staple cartridge to fasten staples to the tissue. The staple cartridge is adjustable to different angular orientations relative to the support tube. The staple actuator mechanism is operable to actuate the staple cartridge in any of the angular orientations. The support shaft is rotatable about its longitudinal axis relative to the handle to adjust the rotational orientation of the support shaft and the staple cartridge. The staple cartridge is rotatable about its longitudinal axis relative to the support shaft to adjust the rotational position of the staple cartridge relative to the support shaft. Separate actuator mechanisms are provided on the handle to control the pivotal movement of the staple cartridge, the rotation of the support shaft, and the rotation of the staple cartridge relative to the support shaft.
